Pituitary tumours are common in dogs and being increasingly recognized cats. usually classified as adenomas should only be carcinomas when there is evidence of metastatic spread the tumour, which rare. Despite benign nature most pituitary tumours, they can still compress or invade neighbouring tissues. functional (hormonally active) non-functional silent). The aim this review was to provide an ...

background and importance: the coexistence of pituitary adenoma and another type of brain tumor is a very rare clinical scenario. even though such a presentation can be an incidental event but the possible pathogenesis of coexistence of different lesions in the sella and suprasellar region has not yet been elucidated. case presentation: two cases of concomitant sellar and suprasellar region tum...

Pituitary apoplexy is a rare clinical event, used to occur spontaneously. Although, some predisposing factors for pituitary apoplexy is reported ie. head injury, digital cerebral angiography, bromocriptine therapy, coughing, lumbar puncture for CSF drainage, pneumoventriculography, even during surgery, in the immediate postoperative period and raised intracranial tension. Although pituitary apo...

BACKGROUND Pituitary adenoma is a common intracranial tumor in neurosurgery. Some pituitary adenomas have the characteristics of invasive growth make them unable to be removed completely by surgery leading to easy relapse. Discoidin domain receptor l (DDR1) is a new kind of tyrosine kinase receptor on the cell surface. DDR1 can be activated by tumor microenvironment signal in tumorigenesis, inc...

Recently, Basic and Clinical Neuroscience published an article by Lim et al. (2016)  entitled Co-occurence of Pituitary Adenoma with Suprasellar and Olfactory Groove Meningiomas. They claimed it as the first case of co-occurence of these two malignancies. However, to our knowledge, this is not the first case reported in this regard. We reported the same case scenario in a 61-year-old woman...

BACKGROUND Pituitary adenoma combined with intracranial aneurysm is not rare. Some aneurysms are located inside pituitary adenomas, and most do not rupture. Pituitary apoplexy caused by aneurysm rupture is rare and is easily misdiagnosed as simple pituitary adenoma apoplexy. CASE PRESENTATION In this study, we report one case of rare pituitary adenoma apoplexy caused by the rupture of an ante...

Pituitary adenoma is a benign neoplasm of pituitary gland. adenoma, particularly macroadenoma,may produce mass effect symptoms by compressing surrounding tissues. Due to function as aneuroendocrine organ, may also cause multiple endocrine disturbances. The authors reportthe case 39-year-old male patient presenting with chronic headache and history seizure. MRI imagingrevealed macroadenoma optic...

Background and Importance: Abscess of the hypophysis or pituitary adenoma is a very rare entity, and its preoperative diagnosis could be challenging. The clinical presentation is less specific, and despite the recent advancement in imaging, diagnosis before surgery is still difficult. Case Presentation: We reported two cases of pituitary abscesses in patients aged 38 and 42 years. The first ...

Thyrotoxic Periodic Paralysis (TPP) is a rare manifestation of hyperthyroidism characterized by muscle weakness and hypokalemia. Thyroid-Stimulating Hormone (TSH)-secreting pituitary adenoma is a rare cause of hyperthyroidism. Even more rare is the occurrence of TPP as the first manifestation of a TSH-secreting pituitary adenoma. We report a 31-year-old Asian male patient suffering from TPP cau...

BACKGROUND Although pituitary adenoma is a malignant tumor, it can present as invasive growth in some cases. MicroRNA (miR)-26a has been found to be abnormally highly expressed in pituitary adenoma, indicating possible involvement in pathogenesis. As a known target gene of miR-26a, PLAG1 has abnormally low expression in pituitary adenoma. The correlation between miR-26a or PLAG1 expressional ab...
